Box 4783, Abu Dhabi, United Arab Emirates Abstract.—This paper provides an updated checklist of the United Arab Emirates (UAE) native and alien herpetofauna. The UAE, while largely a desert country with a hyper-arid climate, also has a range of more mesic habitats such as islands, mountains, and wadis. As such it has a diverse native herpetofauna of at least 72 species as follows: two amphibian species (Bufonidae), five marine turtle species (Cheloniidae [four] and Dermochelyidae [one]), 42 lizard species (Agamidae [six], Gekkonidae [19], Lacertidae [10], Scincidae [six], and Varanidae [one]), a single amphisbaenian, and 22 snake species (Leptotyphlopidae [one], Boidae [one], Colubridae [seven], Hydrophiidae [nine], and Viperidae [four]). Additionally, we recorded at least eight alien species, although only the Brahminy Blind Snake (Ramphotyplops braminus) appears to have become naturalized. We also list legislation and international conventions pertinent to the herpetofauna.

  • Uromastyx by Catherine Love, DVM Updated 2021
    Uromastyx By Catherine Love, DVM Updated 2021 Natural History Uromastyx, also known as spiny-tailed or dabb lizards, are a genus of herbivorous, diurnal lizards found in northern Africa, the Middle East, and northwest India. This genus of lizard is in the agamid family, the same family as bearded dragons and frilled lizards. There are 13 recognized uromastyx species, but not all are commonly kept in captivity in the United States. U. aegyptia (Egyptian), U. ornatus (ornate), U. geyri (saharan), U. nigriventris (Moroccan), U. dispar (Mali), and U. ocellata (ocellated) are some of the most commonly kept. Uros dig burrows or spend time in rocky crevices to protect themselves from the elements in their desert habitats. These lizards naturally inhabit rocky terrain in very arid climates and are often found basking in direct sunlight. Characteristics and Behavior Uros tend to be quite docile and tolerant of handling, with some owners even claiming their lizard seeks out interaction. These lizards don’t tend to bite, but can be skittish if time is not taken to tame them. Ornate uromastyx have been noted to be bolder, while Egyptian and Moroccan uromastyx may be more shy. As with other members of the agamid family, uromastyx do not possess tail autotomy (they can’t drop their tails). Uros are heat loving, mid-day basking lizards that thrive in arid environments. Uros have a gland near their nose that excretes salt, which may cause a white build-up near their nostrils (keepers affectionately refer to this build-up as “snalt”). They are fairly hardy and handleable lizards that make good pets for intermediate keepers.

  • Review of the Taxonomy of the Spiny-Tailed Lizards of Arabia (Reptilia: Agamidae: Leiolepidinae: Uromastyx)
    FAUNA OF ARABIA 23: 435–468 Date of publication: 15.07.2007 Review of the taxonomy of the spiny-tailed lizards of Arabia (Reptilia: Agamidae: Leiolepidinae: Uromastyx) Thomas M. Wilms and Wolfgang Böhme A b s t r a c t : Currently six species of the genus Uromastyx (Reptilia: Agamidae: Leiolepidinae), representing three phylogenetic lineages, are known to occur in Arabia: Uromastyx aegyptia, U. benti, U. leptieni, U. ornata, U. thomasi and U. yemenensis. The present paper gives an overview of the taxonomy of these lizards and presents new data on the morphology and ecology of Uro- mastyx leptieni. ������� ������ ��� � ����� ����� ������ ������� ������ (Leiolepidinae: Uromastyx :��������� :�������) ���� ��������� ����� ����� (Leiolepidinae :��������� :�������) Uromastyx ���� �� ����� � ������� ������ ��� � ������ ���� :���� .U. yemenensis � U. benti, U. leptieni, U. ornata, U. thomasi, Uromastyx aegyptia ���� ������ ����� � � ����� .Uromastyx leptieni ����� ������� ������ ����� ����� ����� ����� ������ ��� ������ ������ ����� ���� INTRODUCTION Spiny-tailed agamas are small to medium-sized, ground- or rock-dwelling lizards. Most species reach a maximum length of 25-50 cm, and only species of the Uromastyx aegyptia group can reach a total length of up to 70 cm or more. The animals have a bulky, depressed body and strong, short limbs. The tail is covered by spiny scales, arranged in distinct whorls. The tympanum is visible. None of the species has a nuchal or dorsal crest or a gular pouch or fan. Only a transverse fold at the throat is present (gular fold). Body scales are small and mostly homogenous, but some species have enlarged tubercular scales on the body and/or limbs. The main diagnostic character of the genus is the highly specialised tooth-like bony structure replacing the incisor teeth in the upper jaw in adults. This transformation of the premaxillary bone to a tooth-like structure is an autapomorphy of the genus Uromastyx, convergent in Sphenodon, which has also a convergently acrodont dentition.

    Study of Halal and Haram Reptil (Dhab "Uromastyx aegyptia", Biawak "Varanus salvator", Klarap "Draco volans") in Interconnection-Integration Perspective in Animal Systematics Practicum Sutriyono Integrated Laboratory of Science and Technology State Islamic University Sunan Kalijaga Yogyakarta - Indonesia Correspondency email: [email protected] Abstract Indonesia as a country with the largest Muslim population in the world, halal and haram being important and interesting issues, and will have more value if being related to science and religion. The research aimed to study halal and haram of reptiles by tracing manuscripts of Islam and science, combining, analyzing, and drawing conclusions with species Uromastyx aegyptia (Desert lizard), Varanus salvator (Javan lizard), and Draco volan (Klarap). The results showed that Dhab (Uromastyx aegyptia) (Desert lizard) is halal, based on the hadith narrated by Muslim no. 3608, hadith narrated by Al-Bukhari no. 1538, 1539. Uromastyx aegyptia are herbivorous animals although sometimes they eat insects. Javanese lizards (Varanus salvator) in Arabic called waral, wild and fanged animals is haram for including carnivores, based on hadith narrated by Muslim no. 1932, 1933, 1934, hadith narrated by Al-Bukhari no. 5530. Klarap (Draco volans)/cleret gombel/gliding lizard is possibly halal because no law against it. Draco volans is an insectivorous, not a wild or fanged animal, but it can be haram if disgusting. Draco volans has the same category taxon as Uromastyx aegyptia at the family taxon. Keywords: Halal-haram, Reptile, Interconnection, Integration, Animal Systematics. Introduction Indonesia as a country with the largest Muslim population in the world, halal and haram are an important and interesting issues and will have more value if being related to science and religion.

Description of two new taxa. 1 2 3 JOSÉ ANTONIO MATE0 ·3, PHILIPPE ÜENIEZ , LUIS FELIPE LÓPEZ-JURAD0 & JACQUES BONS2 I Estación Biológica de Doñana-CSIC, Apartado 1056, E-4108 Sevilla, Spain. 2laboratoire de Biogéographie et Ecologie des Vertébrés-EPHE, Université Montpellier 2, Place Eugene Bataillon, F-34095 Montpellier, France. 3 Departamento de Biología, Universidad de las Palmas de Gran Canaria, 35017 las Palmas de Gran Canaria, Spain. E-mail: luisfelipe. lopez@biologia. ulpgc. es Abstract: The description of a new species ofthe genus Uromastyx is proposed on the basis oftwo specimens from the Adrar Souttouf in Western Sahara. This taxon differs greatly from U. acanthinura on account its larger size, the much larger number of scales, the arrangement of tubercules on its upper thighs, the different habitus and colouring. These morphological features mean it closely resembles U. aegyptia. The existence of a relictual U. aegyptia-group throughout the Sahara is suggested. In addition, the morphological variations in Spiny-tailed agamas (or Mastigures) ofthe Uromastyx acanthinura group in the west ofthe Sahara are briefl y analysed. This produces evidence for the existence of a species proper to Western Sahara and surrounding areas, Uromastyx jlavifasciata, represented by two subspecies: U. f jlavifasciata in the north and U. f obscura subsp. nov. in the south. The latter new form is characterised by uniformly black colouring, even in active individuals. This work also demonstrates that Uromastyx acanthinura werneri does not penetrate Western Sahara and that its distribution is parapatric with that of U.

We assessed the taxonomic relationships within the genus Uromastyx Merrem, 1820 using morphologi- cal and genetic methods, resulting in the resurrection of the genus Saara Gray, 1845 for Saara hardwickii, S. as- mussi and S. loricata and in changes of the taxonomic rank of Uromastyx nigriventris, U. aegyptia leptieni and U. shobraki. A synopsis of all taxa considered to be valid is provided, including differential diagnosis, description and data on their respective distribution. A key for the species of Saara and Uromastyx is presented. Keywords. Reptilia; Sauria; Agamidae; Uromastycinae; Uromastyx; Saara; Saara hardwickii; Saara asmussi new comb.; Saara loricata new comb.; Uromastyx aegyptia leptieni new status; Uromastyx nigriventris new status; Uromastyx sho- braki new status; Phylogeny; Taxonomy; Morphology. 1.
